Hello Peter,
It is possible to use shaders for this purpose if you don't have to use
only pix_ objects.
For exemple, get the result of a dot product between the normalized
background color and the normalized texels colors. Then use a threshold
to determine if a pixel need to be transparent or not
Hi list,
just wondering if anyone has looked into a way to subtract a background
in Gem pixes using a hybrid approach between frame difference
[pix_movement] and difference to a static snapshot [pix_background]. I
want to be able to detect object in front of a background also during
slow light
